You can use the Bits object with the specified size of the variable to implement

The c ++ container has a bitset object, but I think the biggest problem is that the definition must specify the constant size, for example

Bitset <3> bit;

Unable to implement

Int n = 3;

Bitset <n> bit;

So I checked some information and implemented the Bits that can be defined with variables.

Class Bits
{
Public:
Bits (int numOfBits );
Virtual ~ Bits ();
Bool Set (int arg );
Bool Clr (int arg );
Bool Test (int arg );

Class BitsProxy
{

.....

};

Const BitsProxy operator [] (int index) const;
BitsProxy operator [] (int index );

Friend class BitsProxy;


Protected:
Private:
Int * m_pBits;
Static int mask;
Int numOfBits;

};

You can read or assign values to corresponding bits. For example:

Std: cout <bit [3] <std: endl; // bit is a Bits object.

Bit [3] = 1;
